How can PHP variables be accessed within an HTML context for form pre-filling purposes?

To access PHP variables within an HTML context for form pre-filling purposes, you can simply echo the PHP variable value within the HTML input field using the `<?= ?>` or `<?php echo ?>` tags. This allows you to dynamically populate form fields with data stored in PHP variables. 

&lt;input type=&quot;text&quot; name=&quot;username&quot; value=&quot;&lt;?= $username ?&gt;&quot;&gt;
